Folia numerosa 20-24 cm. longa lineari-cuneata trifoliolata, foliolis 

 10-12 cm. longis. Scapi foliis ± duplo longiores ; inflorescentia foeminea 

 oblonga ±16 cm. longa, bracteis subangustatis ± 4 cm. longis apice trifolio- 

 latis umbellas amplectentibus ac paene celantibus. 



Leaves numerous, 20-24 cm-, long, linear-cuneate in outline, trifoliolate 

 (rarely unifoliolate or with 2 pairs of pinnae) ; leaflets 10-12 cm. long, 

 narrow (6-9 mm. in greatest width), rigid and coriaceous, acuminate, 

 pungent-pointed, striate, midrib prominent channelled yellow, edges yellow 

 and finely crenulate, petiole long narrow ; sheaths as long as the petiole 

 or shorter, narrow, membranous, smooth, not striate, expanded towards the 

 base, with 2 short weak linear-subulate lateral spines at the top. 



Scapes twice as long as the leaves, deeply grooved, ± 6 mm. in diameter ; 

 male inflorescence ± 23 cm. long, narrow lanceolate, bracts numerous with 

 obcuneate rather narrow membranous sheaths ending in a long terminal 

 leaflet (10 cm. long in the lowermost bract), flanked by 2 short weak subu- 

 late acicular spines ; umbels small, several, distantly seated on a stout 

 peduncle 9 cm. long below but shortening towards the top of the in- 

 florescence, involucral bracts conspicuous, broadly linear-subulate, 3 cm. long
